Good work, Ruthie. Your coin is from France, just as you suspect. It is a 2 sols piece often known as a 'sou' or 'sou marque.' These are small, low-value coins made out of billon which is a mixture of silver and other metals, usually copper. The silver content varied, but was often around 15-20%. Well preserved coins often look silvery, while very circulated coins can take on a coppery appearance.

Even though these are old, they are not especially rare. Over 8 million of the 1739 date were made. Many were exported from France to Canada and Louisiana, which were at the time territories of the French Crown.
